Rainbows, like the one shown below, form when sunlight passes through raindrops and is separated into different colors.
What happens to the sunlight when it passes through the raindrops that causes the rainbow to form?
A.
The sunlight travels in a straight line through the raindrops.
B. The sunlight is absorbed by the raindrops.
OC.
The sunlight is reflected off of the raindrops.
D.
The sunlight is bent and redirected by the raindrops.
Answer:
D. The sunlight is bent and redirected by the raindrops
Explanation:
This is refraction of light.Understand clearly the difference between reflection which is the bouncing back of light on shiny smooth surfaces and refraction is the bending of light therefore when the sun rays hit the raindrops it is bent and the light is split from a white colour to seven colours known as spectrum

. The number and type of prey items found in the owl pellet can be the result of the following factors: availability and abundance of prey, the ease or difficulty of catching the prey, and the taste preference of the owl. Create an experimental design that would describe the diets of barn owls while accounting for these factors.
Explanation:
Experimental design based on the factors mentioned
Check for availability of prey in same habitat as the Barn owl
Determine the type of prey available in the habitat because Owls feed mostly on small rodents like mice, vole e.t.c
If there is an abundance of prey, Check for the most common and easy to catch prey for an owl . considering the taste of the Barn owls while carrying out this experiment .
The Barn Owls feed mostly on Field voles to other kinds of rodents. therefore the availability and ease of catching a Field vole should be prioritized if they are readily available in the same habitat with the Barn Owls. if Field voles are not available the Barn owls can also feed on other rodents and smaller birds available .
Conclude your experiment
The diets of barn owls depend on the availability and abundance of prey, the energy requires to catch the specific prey, and taste preference based on its behavior.
What do you mean by Prey?Prey may be defined as an animal or any other organism that is hunted or killed by another animal for the purpose of food.
Barn owl decides its food on the basis of availability and abundance of prey because in order to survive barn owl checks the presence of a particular prey that are easily available and found in high number. Mostly barn owl prefers small species of rodents like mice, young one of rabbit, and sometimes birds.
Other than this it also depends on how much energy is required to catch the particular prey because if the energy is greater than that of benefit, barn owls eliminate this behavior.
And last barn owls choose those prey that is palatable in nature and have good taste. Bad taste or toxic taste is eliminated in nature.
Therefore, the diets of barn owls depend on the availability and abundance of prey, the energy requires to catch the specific prey, and taste preference based on its behavior.

Which of the following best illustrates evidence from comparative anatomy that
supports biological evolution?
A:Different Species that have body structures with multiple functions
B: Different Species that have similar bone patterns
C: Similar species that have body structures with different functions
D:Similar species that have different bone patterns
Answer:
The answer is Different Species that have similar bone patterns. I am pretty sure.
Explanation:
The biological evolution is evident from different species having similar bone structure. Thus, option B is correct.
The evolution is a process of inheritable changes in the organism over the time. The species develops from the ancestral have similar structures.
What is the evidence of Comparative anatomy?The comparative anatomy is the analysis of the pattern of evolution. The anatomy is dived with organisms belonging to same genus but have different species.
The organism of different species and same genus have similar structure, with the evolution of the functions. Thus, the evolution is evident with the organism of different species with same structure are belonged to same genus.
Hence, the biological evolution is evident from different species having similar bone structure. Thus, option B is correct.

Part D A scientist comes up with an idea to reintroduce a shark that eats lionfish into the Atlantic Ocean. What are the possible benefits and risks of this idea? In your answer, state two questions you’d ask the scientist before agreeing to the plan.
Answer:
The shark may balance out the lionfish population. However, its presence in the ocean may also negatively affect other organisms. The shark may start preying on natural species, leaving little food for native predators. Two questions to ask the scientist are, Does this shark have any natural predators in the Atlantic Ocean to help control its population numbers? and What other organisms does the shark eat?
Explanation:
i got this from edmentum-
Although some species of grouper and shark may be able to eat them, lionfish have relatively few predators in the area they have invaded because of their deadly spines. Although lionfish are widely distributed, most sharks won't readily eat them.
What eats lionfish into the Atlantic Ocean?The shark might maintain lionfish populations in balance. Its presence in the ocean, however, might also have a harmful impact on other organisms. It's possible that the shark will start eating native animals, leaving little food for them.
Do this shark's natural predators in the Atlantic Ocean aid to regulate its population numbers? Are two queries to put to the expert. What other kinds of creatures does the shark consume?
Therefore, Because the Moray was discovered in a location where divers would not have been searching, this is the first confirmed instance of natural predation of the invasive lionfish in the Atlantic Ocean.

Fernanda is feeling sick and goes to the
doctor. Upon taking a blood sample, the
doctor observes that Fernanda's cells
contain a pathogen that seems to be made
of small cells with no nucleus. What type of
infection does Fernanda have?
bacterial
fungal
none of the above
viral
Answer:
bacterial
Explanation:
A prokaryotic organism is an organism that does not possess a membrane-bound nucleus that houses its genetic material. Organisms grouped under this domain are bacteria, archaebacteia etc.
According to this question, Fernanda goes for a blood sample because she felt sick. The result of the blood sampling shows that the cells of Fernanda contain a pathogen that seems to be made of small cells with no nucleus. This property describes a prokaryotic pathogen. Hence, the infection is most likely to be that of a BACTERIAL INFECTION.
Note that, a fungus is eukaryotic while a virus is considered non-living because it can only replicate in a living host.

Which of the following statements best describes the replication of DNA?
a. The double helix unzips the hydrogen bonds between bases and like bases pair up (G with G, C with C, etc.)
b. The double helix unzips at the phosphate bonds and new nucleotides pair with the appropriate sugars.
c. The double helix unzips the hydrogen bonds between bases and new DNA nucleotides pair with the complementary bases in the old strands.
d. The double helix unzips and RNA forms base pairs with the complimentary strand of DNA.
Answer:
By hydrogen bonds between nucleotide bases
Explanation:
A DNA molecule is a double-stranded molecule that is informing one structure two strands of nucleotide are involved.
The double-stranded molecule backbone is composed of the phosphate and sugar group and the inside of the backbone are presents the nitrogenous bases. The nitrogenous bases are of four types which are: adenine, cytosine, guanine, and thymine.
These nitrogenous bases are attached according to the Chargaff rule that is adenine binds thymine and cytosine binds guanine. These bases bind with the help of the hydrogen bond as 2 hydrogens participate between adenine and thymine and 3 hydrogens participate between cytosine and guanine.
Thus, hydrogen bonds between nucleotide bases is correct.
